3 Description
The DRV8816 provides a versatile power driver
solution with two independent ½-H bridge drivers.
The device can drive one brushed DC motor or one
winding of a stepper motor, as well as other devices
like solenoids. A simple INx/ENx interface allows
easy interfacing to controller circuits.
The output stages use N-channel power MOSFETs
configured as ½-H-bridges. The DRV8816 is capable
of peak output currents up to ±2.8 A and operating
voltages up to 38 V. An internal charge pump
generates needed gate drive voltages.
A low-power sleep mode is provided which shuts
down internal circuitry to achieve very-low quiescent
current draw. This sleep mode can be set using a
dedicated nSLEEP pin.
Internal protection functions are provided for UVLO,
charge pump fault, OCP, short-to-supply protection,
short-to-ground protection, overtemperature warning,
and overtemperature shutdown. Fault conditions are
indicated through a nFAULT pin
The DRV8816 is packaged in a 16-pin HTSSOP
package with PowerPAD™ (Eco-friendly: RoHS & no
Sb/Br)
